AI Technical Summary
Existing targets require frequent disassembly and alignment during field operations of 3D laser scanners in underground metal mines, resulting in long operation times, high labor costs, and large errors, making it impossible to perform scanning operations efficiently.
Design a target structure that includes a magnet ring and a target disk. The magnet ring is pre-set at a control point, and the fixing rod is fixed inside the magnet ring by magnetic attraction, which simplifies the centering and disassembly process of the target.
It achieves stable fixation of the target in underground metal mines, reduces manual operation time, improves scanning efficiency, reduces errors, and has a simple structure and low cost.

Description
TECHNICAL FIELD
[0001] The utility model relates to surveying and mapping equipment technical field, especially relate to a target for three -dimensional laser scanner field work of metal mine underground. BACKGROUND
[0002] In the surveying and mapping technical field, three -dimensional laser scanner is the new technology of the more popular surveying and mapping field nowadays, and the roadway and goaf of metal mine underground need three -dimensional laser scanner to scan and measure, and the target is as the control point in coordinate conversion and the reference object in point cloud splicing in the field work process of three -dimensional laser scanner, and the point cloud data obtained by scanning is unified to the same independent coordinate system, in general, the target plays two roles, one is that the point cloud data between different stations is spliced together accurately through the control point, and the other role is to control the whole measurement area, and reduce the scanning measurement error.
[0003] At present, more and more roadway projects need to use three -dimensional laser scanner to scan and model, and the existing target is mainly divided into spherical target and plane target two, and the control point with three -dimensional coordinates is arranged at 1m from the ground in the roadway of metal mine underground, and the existing target needs to be centered on the control point by the operating personnel, then fixed, so as to carry out scanning operation, and in the whole surveying and mapping process, the target needs to be constantly disassembled, centered and reinstalled, which is time -consuming and labor -intensive, and when the measurement area is larger, the labor cost increases, and the operating personnel also produces error when centering the target, so the scanning operation cannot be carried out efficiently. Therefore, a target for three -dimensional laser scanner field work of metal mine underground needs to be developed. UTILITY MODEL CONTENT
[0004] In view of the above technical problems, the utility model provides a target for three -dimensional laser scanner field work of metal mine underground.
[0005] In order to realize the above purpose, the technical scheme of the utility model is as follows:
[0006] A target for three -dimensional laser scanner field work of metal mine underground, comprising:
[0007] The magnet ring is arranged on the control point.
[0008] The target disc is arranged on the control point.
[0009] The fixing rod is vertically arranged at the bottom of the target disc, and the bottom is inserted into the magnet ring and is magnetically attracted to the magnet ring.
[0010] The utility model has the advantages of:
[0011] 1. The utility model discloses a magnet ring is arranged on the control point, sets up the target disc, only need the fixed rod of target disc bottom is inserted magnet ring, because magnet ring is arranged in advance on the control point, therefore, need not the fixed rod is centered operation, has saved the operation time, because fixed rod and magnet ring mutual magnetic attraction, therefore, also simple and quick when dismantling.
[0012] 2. The utility model discloses can high -efficiently realize three -dimensional laser scanner in metal mine underground scanning operation can better gather the three -dimensional coordinates of control point, can also make this target steady fixed on the control point, and convenient installation and disassembly target, reduced the operation personnel of need constantly replacing target, improved scanning operation efficiency.
[0013] 3. The utility model discloses compact structure, simple principle, easy to process, low in cost, convenient operation, good use effect, especially in the metal mine underground roadway scanning has the popularization value extremely. ACCURACY OF DRAWINGS

[0018] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, below combining with specific implementation, the utility model is further detailed explanation. Should understand, these descriptions are only exemplary, and not to limit the scope of the utility model. Moreover, in the following explanation, the description of known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.
[0019] As Figs. 1 to 3 Shown, a kind of target for metal mine underground three-dimensional laser scanner field work, including: magnet ring 2, is arranged on control point;Target disc 1;Fixed rod 3, vertically set in target disc 1 bottom, and its bottom is inserted in magnet ring 2, and with magnet ring 2 mutual magnetic attraction.
[0020] The target disc 1 is a circular reflector with cross mark (two opposite corners are black, and the other two opposite corners are white) with diameter of 8cm.
[0021] The use process of the utility model is:
[0022] In use, the magnet ring 2 is set on the control point in advance, the target disc 1 is connected with one end of the fixed rod 3 at the center of the circular reflector with cross mark (two opposite corners are black, and the other two opposite corners are white), the magnet ring 2 is sleeved on the other end of the fixed rod 3, and the end of the fixed rod 3 is sleeved on the control point, so that the target is centered on the control point, and the firmness of the target and the control point is improved.
[0023] It should be understood that the above specific embodiments of the utility model are only used for example or explanation of the principle of the utility model, and do not constitute the limitation of the utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without deviating from the spirit and scope of the utility model shall be included in the protection scope of the utility model. In addition, the utility model claims to cover all changes and modifications falling within the scope and boundaries of the appended claims or the equivalent forms of such scope and boundaries.
